Credit Utilization Optimizer: Time Card Payments to the Statement Date
The balance your cards report is the one on each statement closing date, not the one left after you pay the bill. Enter your cards and the cash you have, and get a dated plan that makes the reported balances as low as possible before a mortgage, auto loan or apartment application.
Everything runs on the numbers you enter; nothing is sent anywhere. Card issuers usually report the balance on your statement closing date, not the balance left after you pay the bill.
Your cards
Leave unused rows blank. The statement closing date and the payment due date are printed on each statement.
Your plan
| Card | Pay | Pay by | Statement closes | Balance it reports | Utilization | Then pay by |

"Pay by" is three days before the closing date, so the payment posts in time. "Then pay by" is the due date for the smaller statement that follows; pay that statement in full to avoid interest.
How the Optimizer Works
A card issuer typically reports your account to the credit bureaus once a month, with the balance on the statement closing date. That balance, divided by the card's limit, is the card's utilization, and the total across your cards is your overall utilization. Paying by the due date keeps you clear of interest, but the report has already gone out by then. Paying before the closing date is what changes the number the bureaus see.
Overall utilization falls by the same amount whichever card you pay, so the optimizer uses your cash to cut the fullest card first. It lowers the cards with the highest utilization to a common level, then keeps lowering them together until the cash runs out: for the money you have, no plan leaves a lower highest-card utilization. With enough cash it pays everything off.
The all-zero-except-one goal pays every card to zero before its statement closes except one, which reports the small balance you choose. It keeps that balance on the card where it matters least, the one with the highest limit among those carrying at least that much. If your cash falls short of what that takes, the optimizer tells you how much is needed and spreads the cash instead.
For each card the plan lists the next statement closing date after your start date, a pay-by date three days earlier and the due date of the statement that follows. If a statement closes within three days, pay now and expect the payment to show on the following statement.
Reading the Result
With the example cards, $3,000 of cash takes overall utilization from 34% to 16% and the fullest card, a $2,000 card at 90%, down to about 19%. Bringing every card under 30% would take $2,200, every card under 10% $4,100, and all zero except one $5,775.
Read the plan as a timeline. Make each payment by its pay-by date, then leave that card alone until the statement closes; anything you charge in between is added to the balance it reports. Once the statement posts, pay it in full by the due date. If your application is weeks away, you can repeat the plan in the next cycle.
What the Optimizer Leaves Out
It does not estimate score changes: models weigh utilization differently, and the effect depends on the rest of your credit file. Some issuers report on a date other than the statement closing date, or more than once a month, and payments can take a few days to post. New charges between your payment and the closing date raise the reported balance. Cards with no limit set, such as some charge cards, are left out of the utilization math. And classic scores forget old utilization, while trended-data models such as FICO 10T and VantageScore 4.0 also look at how your balances have moved over time.
